    Organic Light-Emitting Diode (OLED) advantages like as thin, flexible, transparent, long life, environmental friendly and it’s optical efficiency is better than conventional light source. However, OLED are planar source in combination with a Lambertian angular light distribution causes central brightness decline. In this paper, in order to control OLED light viewing cone to focus within ± 30 degrees and improve the center’s view of the brightness, we design the optical element (micro-structure and reflector) by ASAP software simulate the enhancement effect and optimize the micro-structure parameters. With the use of an optimized micro-structure, the center’s view of the brightness increase about 110%. We develop the OLED tail lamp prototype to verify this design can effectively enhance the brightness about twice and the light pattern consistent with the needs of tail lamp.
